What is the surface area of a sphere with a circumference of 30 ft?
286.5 ft
Summary: The surface area of a sphere with a circumference of 30 ft is 286.5 ft.
How do you find the circumference of a sphere?
Circumference of a sphere: C = 2πr.
What is the surface area of a ball that has a radius of 10cm?
Calculate the surface area of a solid hemisphere of radius 10 cm. Substitute. So, the surface area of the sphere is 942 cm2.
Why is surface area of sphere?
The surface area of a sphere is always expressed in square units. The formula for the surface area of a sphere depends on the radius and the diameter of the sphere. It is mathematically expressed as 4πr2; where ‘r’ is the radius of the sphere.
How do you find the surface area of a dome?
2 × π r × h square units. If, for example, h = r so that the dome (light blue) is half of the sphere then the surface area of the dome is 2 π r2 square units, twice the area ofthe base (dark blue). If h is very small then the area of the cap can be much smaller than the area of the base.
How do you figure surface area?
The total surface area is calculated by adding all the areas on the surface: the areas of the base, top, and lateral surfaces (sides) of the object. This is done using different area formulas and measured in square units. Volume is the amount of space that a three dimensional object takes up.
What is the volume of a spherical dome?

How do you find the surface area of a circle?
The area of a circle is pi times the radius squared (A = π r²).
How do you calculate the surface area of a dome?
2 × π r × h square units. If, for example, h = r so that the dome (light blue) is half of the sphere then the surface area of the dome is 2 π r2 square units, twice the area ofthe base (dark blue).
If sphere volume is given, then Circumference C = π2/3(6V)1/3 Radius r = (3V / 4π)1/3 Surface Area A = π1/3(6V)2/3 Where, r is the sphere radius V is the volume of a sphere C is the sphere circumference A is the sphere surface area Steps to Solve Sphere Area, Circumference, Volume
How to calculate sphere volume and surface area using RADIUS?
Below mentioned are the basic and straightforward formulas to compute the sphere volume, circumference, and surface area by using the radius. Volume of a Sphere Formula: Volume V = (4/3)πr³ Circumference of a Sphere Formula: Circumference C = 2πr Surface Area of a Sphere Formula: Surface Area A = 4πr² Sphere Calculations:
What is the difference between a sphere and a shape?
Whereas the sphere is a three-dimensional shape having surface area and volume. Area and Volume Calculator
